I've made a site that uses CSS. On the interior pages, when I'm using Safari or Firefox, all of the pages look fine. When I look at the pages in Firefox on a PC, they look the same; however, in Explorer 7 on a PC, the background image is misaligned. In addition, the DIVs have spaces between them.

Have I done something wrong, or is IE breaking the pages? Is there a snippet that will make the pages display properly?
